Application fil d October 22, 1901. Serial No. 79,597. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT S. REEVES, a resident of Bridgeton, in the county of Cumberland and State of New Jersey, have invented certain new and useful Improvements in Bottle-Making Machines; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in bottlemaking machines, the object of the invention being to provide machines of this character which can be operated to rapidly and uniformly press and blow bottles into shape and dispense with the necessity of handling the glass or molds until the bottles are blown.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a View, partly in section, illustrating my improvements. Fig. 2 is an end view, partly broken away and in section. Fig. 3 illustrates the carriage. Fig. 4c is a View of the mold. Fig. 5 is a View of the plate 22, and Fig. 6 is a view in cross-section of the trackframe.

1 represents standards on which an elongated track-frame 2 is supported, and the latter has secured thereto at its ends the respective ends of an arched frame 3, located above the track-frame for a purpose which will hereinafter appear.

The track-frame 2 comprises parallel sides 4, ends 5, and a slotted bottom 6, the adjacent faces of the sides made with alined parallel flanges 7, forming a track 8 of the peculiar shape shown in Fig. 1, and horizontal alined flanges 9 are provided on the inner faces of the sides near their upper edges, forming a second track or guide, the purpose of which will now be explained. On this upper horizontal straight track 9 the projecting edges of a plate 10 are mounted to slide, said plate 10 having secured to its lower face a depending bracket 11, which, together with the plate 10, forms a movable carriage for the bottle molds 12. The plate 10 is made with a central opening large enough to permit the free movement therethrough of a plunger or blank 13. This plunger or blank 13 is preferably of the shape shown--namely, with an enlarged head or upper end-and is secured at its lower end to a cross-bar 14, having trunnions at its ends mounted to move in longitudinal slots in bracket 11 and carrying rollers 15, adapted to move in the tracks 8 and raise and lower the plunger or blank 13 as the rollers move through the varying angles of the track. To propel the carriage, I provide a lever 15, secured on a shaft 16 and connected by pivoted links 17 and 18 with an arm 19 on plate 10, so that by shifting the lever 15 the carriage can be moved from end to end of the track-frame and stopped where desired.

The carriage is adapted to convey a mold 12, which is preferably of the shape shown or maybe of various shapes, according to the article to be molded, the mold resting on plate 10 directly over the opening therein and having a wide groove 21 in its base to receive plates 22, (a plate 22 being secured at each end of the track-frame by means of screws 20, passed through one end and into the end 5 of the frame.) These plates 22 project in a horizontalline toward the center of the frame and are preferably slightly wedge-shaped, as shown,-and when the carriage, with the mold thereon, is moved to either end of the frame the plate 22 will enter the groove 21 in the mold and support the latter, permitting the carriage to be moved from under the same.

At each end of the frame and above the point on plate 22 where the mold 12 is deposited an air-blast valve 26 is provided, the construct-ion of these valves and operating parts being precisely alike. The below description of one will apply alike to both. A bracket 23 projects inward from the end portions of arched frame 3 and has secured to its free end a valve-chamber 2 1, having an air-duct 25 in one side, a nipple being formed at the inlet end of said duct, by means of which a flexible hose may connect the valve-chamber with a suitable air-reservoir 26", communieating with a pump and reservoir 26*, a pump being preferably provided for each end of the machine and the pumps having a common plunger-rod 27 for the plungers therein. This plunger-rod 27 may be connected with the carriage, so as to operate both plungers by the movement thereof, or the rod may be provided with independent operating mechanism, as preferred.

The valve-chamber 24 is made with a vertical bore communicating with duct 25 and has mounted therein a valve 26, projecting above and below the casing and made with an angular duct 27, which when the valve is depressed communicates with duct 25 and permits the free passage of compressed air through the lower end of the valve. To operate this valve, I provide the chamber 24 with an arm 27*, projecting outward therefrom, and to the outer end of which a lever 28 is pivoted and connected at its other end to the upper protruding end of valve 26. This lever 28 has connected between its ends a link 29 the lower end of which latter being connected to a treadle29 for operating the valve in one directionnamely, forcing it downwarda spring 30 being provided below the treadle to return all of said parts to their normal positions.

Mounted to slide vertically in the center of the arched frame 3 is a plunger-frame 31, comprising parallel vertical rods and connectingbars 32, forming a rigid frame. A screw threaded plunger-rod 33 is mounted in said cross-bars and disposed centrally between the vertical rods and adapted to be adjusted vertically to secure the best results. The lower end of the plunger-rod 33 is made smooth and contracted to form a plunger 34, mounted in a sleeve or tube 35, the latter having a cross-head 38 and vertical pins 36 at the ends thereof. These pins project up through holes in a cross-bar 37, screwed onto plunger-rod 33, and the pins are provided above this cross-bar 37 with stops to prevent the escape of the pins through the holes in the end of the bar. Coiled springs 39 are located on pins 36 and exerta downward pressure on the sleeve 35 to normally hold the same in posi tion to inclose the plunger 34.

The plunger-frame 31 is lowered by means of a lever 40, secured on one end of a shaft 41, mounted in bearings 42, depending from frame 3 and made with crank-arms 43, projecting at right angles thereto and connected by links 44 with the ends of connecting-bar 2 at the top of frame 31, so that by exerting a pull downward on lever 40 the plungerframe 31 will be forced downward, and when the power is removed from lever 40 the plunger-frame 31 will be raised to its normal elevated position by means of counterweighted levers 45, fulcrumed between their ends on standards 46, secured on frame 3 at opposite sides of the plunger-frame. The inner ends of the counterweighted levers 45 are held be tween adjustable nuts or shoulders 47 on plunger-rod 33, so that the weights, which are on the outer ends of said levers, will return the plunger-frame to its elevated position and hold it there until the lever 40 is again operated.

The operation of my improvements is as follows: When the carriage is in the center of the track-frame, as shown in full lines in Fig.1, the plunger or blank 13 is in its highest position in mold 152 and the space in the mold above the plunger 13 is filled with glass. The lever 40 is now operated to depress the plunger-frame 31, when sleeve or tube 35 will be forced down on the mold, closing the opening in the top thereof. A continued downward movement of lever 40 serves to force the plunger 34 into the glass, forming a recess therein, and when the lever 40 is released counterweighted levers 45 will return the plunger-frame 31 to its raised position. The shifting-lever 15 is now operated to move the carriage to the right, and such movement thereof will, owing to the peculiar shape of the track 8, as above explained, draw the plunger 13 down out of the mold 12 and permit the plate 22 to enter the groove 21 in the mold and support the same independent of the carriage. The mold will then be disposed directly below valve 26, when the latter will be pulled down through the medium of treadle 29, as heretofore pointed out, and will enter the recess in the glass formed by the plunger 34 and direct a blast of air into the glass to blow the bottle. When the hottle is formed, the treadle 29 is released to depositing the mold on plate 22, the shiftinglever 15 is moved in the opposite direction to shift the carriage to the center beneath the plunger '34 once more, a new mold having been placed on the carriage, the operation of punching a recess in the glass is repeated, and the lever 15 moved to convey the carriage to the left, when the mold will be deposited on the plate 22 at this end of the machine and the blowing operation is carried out as explained in connection with the other side of the machine. The carriage is again moved to the center and the operation above described is repeated, and it will be seen that by employing my improved machineI am enabled to press the glass in the molds, pressing a recess in the glass at the same time, and blow the bottles in the mold without manually handling the molds at all, thus insuring accuracy in the articles made and cheapening the cost of manufacture. 7

Various slight changes might be resorted to in the general form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I would have it understood that I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention. Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a bottle-making machine, the combination with a mold and a carriage, of a plun ger for pressing a recess in the glass in the mold, another plunger supported in the carriage and movable with it to support the glass in the mold, means for moving the carriage away from said first-mentioned plunger, and means for automatically removing the mold and its contents from the carriage and the plunger carried thereby when they have been moved away from the first-mentioned plun' ger.

2. In a bottle-making machine, the combination with a mold having a groove in its base, and a mold-carriage, of a device for pressing a recess in the glass in the mold, a plunger mounted in the carriage to support the glass in the mold, means for moving the mold away from the pressing device, and a fixed plate to enter the groove in the mold to remove the latter from the carriage and the plunger therein, when the carriage and plunger have been moved away from said pressing device.

3. In a bottle-making machine, the combination of a mold and a movable carriage adapted to support the mold, a plunger for pressing a recess in the glass in the mold, automatic means for removing the mold from the carriage when the latter is moved to a predetermined position, means for directing a blast of air into the recess in the glass when the mold is removed from the carriage, and mechanism operated by the carriage for generating the air-blast.

4. In a bottle-making machine, the combination with a track, a mold-supporting carriage movable thereon and means for moving the carriage from one end to the other of said the frame so shaped as to raise the plunger in the mold when the carriage is moved to the center of the frame and draw the plunger out of the mold when the carriage is moved to either end of the frame, a plunger frame mounted above the center of said first-mentioned frame, alever for depressing said plunger-frame, a sleeve adapted, when the plunger-frame is depressed to exert a spring-pressure on the mold to close the open top thereof, a plunger normally inclosed in said sleeve and adapted to press a recess in the glass in the mold, means for removing the mold from the carriage when the latter is moved to one end of the frame, and means for directing an airblast into the glass when the mold is removed from the carriage.

6. In a bottle-making machine, the combination with a track-frame, of a carriage movable from end to end of the frame, a mold supported on said carriage and having a groove in its base, a plunger carried by the carriage, a track adapted, when the carriage is moved to the center of the frame to project the plunger up into the mold and draw the plunger out of the mold when the carriage is moved to either end of the frame, means in the center of the frame for pressing a recess in the glass in the mold, a plate at each end of the frame to enter the groove in the mold and support the mold independent of the carriage, means for compressing air, air-valves at both ends of the frame, and means for operating said valves to direct a blast of air into the glass.

7. In aglass-making machine, the combination with a mold and a mold-support, of means for compressing air, a valve-chamber above the mold-support having an air-duct therein connected with the air-compressing means, a valve in said chamber having an angular duct therein normally out of communication with the first-mentioned duct, means for forcing said valve into the mold so that when so moved the air-ducts will communicate and admit an air-blast to blow the glass.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
